"As governor, you took an oath of office to uphold the entirely godless and secular United States Constitution."

Gaylor and Barker called on Walker "to immediately delete this religious message from your official gubernatorial Facebook and Twitter."

On Sunday, Walker tweeted "Phillipians 4:13" on the @GovWalker twitter handle. This is noted as being the "Official Twitter Account of the 45th Governor of the State of Wisconsin, Scott Walker." Walker has another twitter handle, @ScottWalker.

The @GovWalker tweet of the verse citation received as of Tuesday evening 52 retweets and 76 favorites. It also received diverse responses from other Twitter accounts.

"@curtkrone @GovWalker it speaks volumes of a man who will admit his strength comes from that which is greater than him. #prideBeforeTheFall," tweeted @Jameski07.

"@GovWalker If you TRULY were a person who gained his strength thru Christ, you would stop stealing from the poor to pay the rich. #disparity," tweeted @BadgerStew.

"@GovWalker Isn't this supposed to be your official government twitter account? Whatever happened to the wall of separation?" tweeted @LLchern.

The letter comes not long after Walker appeared in a couple of commercials with characters from Sesame Street to promote healthy eating and exercise for children.
